Meteorite impact suspected to have caused bizarre circular structure in Antarctica

A circular structure with a diameter of 2 km has been recently spotted in Eastern Antarctica, and scientists believe it could be an impact crater produced by the fall of a meteorite fragment as big as a house, a decade ago.

The structure was found in the middle of a flat expanse of ice during a research flight over Antarctica. At the center of the large round “scar” there are blocks of broken ice surrounded by other smaller circular structures.

The observations lead to the hypothesis that a meteorite the size of a house would have disintegrated in Earth’s atmosphere over the Antarctic , before the remains fell over the ice cap.

An international team of scientists continue to analyze data; at this point they can not say precisely if the crater was really created by a meteorite impact, but the two studies support the assumption.

Experts believe that a meteorite with a diameter of about 7-10 meters and a weight estimated at 600-1900 tonnes was traveling at a speed of 46 km/s and it exploded with a force equivalent to the 12,000 tons of TNT.
